Hello, everybody.
Recently, I consider to buy a pre-amp.
My friend suggest that DCB1 is a good pre-amp.
So, I consider to build DCB1. But, I do not know where I can buy DCB1 kit (include PCB and electronic components).
Who can show me?
Thank you!

This would just need a 50VA 15-0-15V transformer, a case and a little bit of hardware to complete. Apparently the bigger the better, I use a 60VA transformer with mine but 30VA is more than adequate until you start pushing the PSU into HOTROD territory.

Its not fussy about 15-0-15V either. If you have something bigger (say 25-0-25) it will still work but will just need a bit of heatsinking. The initial 4700uF caps also need to be rated to cope with any increased input voltage. Everyhthing else else should be fine.

Speak to me nicely and I can help you out with some of the hardware that you might need.
